An organic light emitting diode (OLED) display includes a substrate, a thin film transistor (TFT) on the substrate, an OLED connected to the TFT and configured to emit white light, and a capping layer on the OLED. The capping layer includes a first high refractive index layer, a first low refractive index layer, a second high refractive index layer, and a second low refractive index layer that are sequentially stacked.
